"If you look at what we're trying to accomplish, which is deliver value for marketers and consumers, does a platform like APT and RMX get us that much closer? The answer is probably not."

That doesn't mean a sale is imminent. It'd be quite an ordeal.

"This platform has been intertwined into the whole ad-serving process. It's not like they can just rip it out and sell it real quick. People are underestimating the intricacy."

After conversations with Yahoo CEO Scott Thompson, this source – who asked to remain anonymous as he is not an official spokesperson – says its pretty clear Thompson is not going to be rushed into any sale.

"I've gotten to know him well enough to know that he's a really smart guy and a smart business man: he's not going to get bullied. He's not going to sell the Asian assets cheap and the same goes for RMX. He's exploring all options."
